no. 1 approach

[0031] Hereinafter, the first embodiment will be described. The vehicle-mounted system of this embodiment is mounted on a vehicle. Such as figure 1 As shown, the on-board system has an engine EG and an air conditioner. Engine EG is an internal combustion engine that generates driving force for running the vehicle. The air conditioner has figure 1 A room air conditioning unit 10 and a refrigeration cycle 30 are shown. The indoor air conditioner unit 10 and the refrigeration cycle 30 constitute an air conditioner. In addition, this air conditioner and a vehicle control device described later constitute an air conditioner system.

[0032] The indoor air conditioner unit 10 introduces external air and internal air, further heats or cools it, and blows it out into the vehicle interior. Thus, the air conditioning in the vehicle interior is performed. In addition, the external air and the internal air are the air outside the vehicle and the air inside the vehicle, respectively...

[0120] Next, a second embodiment will be described. In the in-vehicle system of the present embodiment, the processing contents of the air-conditioning control process 210 and the engine control process 220 are changed from those in the in-vehicle system of the first embodiment.

[0121] More specifically, in the air conditioning control process 210, Figure 4 The suction port mode determines that the handle is replaced by the Figure 7 treatment shown. and, in image 3 In step S10, the vehicle control device controls the inside and outside air switching actuator 221 to arrange the inside and outside air switching valve 23 to realize the outside and inside air switching valve 23 determined in the previous step S8 when the intake port mode is the inside and outside air double-layer mode. The position of the gas introduction ratio P.

[0122] And, in the engine control process 220, Figure 5 The firing timing decision process is replaced by Figure 8 treatment shown. exis...

no. 3 approach

[0132] Next, a third embodiment will be described. In the in-vehicle system of this embodiment, the processing content of the engine control process 220 is changed from that of the in-vehicle system of the second embodiment.

[0133] More specifically, in engine control process 220, Figure 8 The firing timing decision process is replaced by Figure 9 treatment shown. exist Figure 8 and Figure 9 The contents of the processes in the steps indicated by the same symbols are the same.

[0134] In the ignition timing determination process, when the vehicle control device 200 determines in step S255 that it is the dual air mode, the process proceeds to step S243. In step S243, the heat generation increase amount Qc is calculated. The calculated heat generation increase amount Qc is a positive value. However, the calculation method is different from the method in step S270.

[0135] Specifically, in step S243, the vehicle control device 200 calculates the heat generation in...

Abstract

The purpose of the disclosure of the present invention is to appropriately adjust the heat generation amount of an engine in accordance with an outside air introduction rate, in a vehicle in which heating is carried out using engine cooling water. An engine control device that controls the operation of an engine (EG) which generates travel driving-force for a vehicle is provided with the following: an acquisition unit (S250, S251, S305, S306) that acquires state information based on the state of an air conditioning device (10, 30) impacting an outside air introduction ratio, the outside air introduction ratio being defined as a ratio, in the air conditioning device in which air is introduced into an air conditioning casing (11), heated using engine cooling-water and then blown into the vehicle interior, of the air volume of the air introduced into the air conditioning casing from the exterior of the vehicle to the air volume of air introduced into the air conditioning casing from the interior and the exterior of the vehicle; and a ratio trend control unit (S240-S285, 230, 240) that, on the basis of the state information acquired by the acquisition unit, controls the operation of the engine so that the heat generation amount of the engine becomes smaller to a greater extent in a case where the outside air introduction rate is a second rate which is lower than a first rate than in a case where the outside air introduction rate is the first rate.

Description

[0001] Cross-reference of related applications [0002] This application is based on the JP Patent application number 2015-182169 for which it applied on September 15, 2015, The description content is incorporated here by reference. technical field [0003] The present invention relates to a program used in an engine control device, an air conditioning system, and an air conditioning control device. Background technique [0004] Conventionally, there is known an air conditioner that heats air using engine cooling water. In such an air conditioner, when the outside air that is the air outside the vehicle is introduced and blown out into the vehicle interior, the outside air is heated by the cooling water. In this case, since the cooling water is deprived of heat by the outside air, the rise in temperature of the cooling water is delayed. As a result, the heating effect cannot be obtained quickly. [0005] Therefore, a temperature rise control is known in which the engine i...
